1. Paraphrased from a letter entitiled Revelation by Robert C. Manahan:
Patrick F. Manahan (Murnaghan) was from the village of Shercock, near Dundalk in the township of Mullahard, County Cavan, Ireland, near a lake (probably Lake Sillan) separating Counties Cavan & Monaghan. Shercock is reported to be about 20 miles from Cavan Town, the county seat of County Cavan. Patrick is reported to have “runaway” from the UK, and came to Ellis Island, New York at age 16. It is understood that the cost of passage was 6 Irish Pounds. The port of departure was from Cork, Ireland around 1898. He then settled in Briarcliff, NY. It is assumed that Patrick changed his name upon arriving in the USA.
